背景:在青春期使用大麻是一个公共卫生问题,必须通过预防来解决。在西班牙,青少年开始使用大麻的平均年龄为14.8岁。14岁时,大麻使用的终生患病率为11.7%,增加到51。,在18岁时占5%;14至18岁人口中使用大麻的患病率为28.6%,一个必须努力减少的数字,这就是为什么这个学校预防计划被提出:Alerta大麻。
方法:AlertaCannabis研究项目包括设计,实施,和评价。在第一阶段,基于I-Change模型开发了计算机定制的eHealth程序(AlertaCannabis),基于三个主要行为变化过程的集成模型:意识,动机,和行动。该计划包括四个30分钟的课程,将提供文化适应和个性化的建议,以激励学生不要通过文本反馈使用大麻,动画,和游戏化技术。此阶段还将包括可用性测试。在实施阶段,来自西安达卢西亚的中学生,西班牙(塞维利亚,卡迪兹,韦尔瓦,和科尔多瓦)和东部安达卢西亚(哈恩,马拉加,和Granada)将随机分配到实验条件(EC)或对照条件(CC)进行集群随机临床试验(CRCT)。每个条件将在8所学校中有35个班级。GI将收到在线干预Alerta大麻。EC和CC必须在基线时填写问卷,六个月,和12个月的随访。在最后阶段,评估Alerta大麻的效果。主要结果是大麻使用的终生流行率及其在过去30天和6个月的使用。在12个月的随访中,还将评估过去12个月的患病率。次要结果是使用大麻的意图。
结论:该研究测试了创新计划的效果,该计划专门旨在通过西班牙的eHealth减少青少年人群中大麻的使用。调查结果旨在制定和实施基于证据的大麻预防干预措施,这可以支持学校的预防,例如,学校护士的协助。如果该计划被证明是有效的,它可能有助于防止在国家和国际范围内使用大麻。

BACKGROUND: The growing use of cannabis in adolescence is a public health problem that must be addressed through prevention. In Spain, the average age of initiation of cannabis use in the adolescent population is 14.8 years. At 14 years, the lifetime prevalence of cannabis use is 11.7%, which increases to 51.,5% at the age of 18; the prevalence of cannabis use in the population aged 14 to 18 years is 28.6%, a figure that must be tried to reduce, that is why this school prevention program is proposed: Alerta Cannabis.
METHODS: The Alerta Cannabis research project consists of design, implementation, and evaluation. In the first phase, a computer-tailored eHealth program (Alerta Cannabis) is developed based on the I-Change Model, an integrated model based on three main behavioral change processes: awareness, motivation, and action. This program consists of four 30-minute sessions that will provide culturally adapted and personalized advice to motivate students not to use cannabis through text feedback, animations, and gamification techniques. This phase will also include usability testing. In the implementation phase, secondary school students from Western Andalusia, Spain (Seville, Cádiz, Huelva, and Córdoba) and Eastern Andalusia (Jaén, Málaga, and Granada) will be randomized to an experimental condition (EC) or a control condition (CC) for a cluster randomized clinical trial (CRCT). Each condition will have 35 classes within 8 schools. GI will receive the online intervention Alerta Cannabis. EC and CC will have to fill out a questionnaire at baseline, six months, and twelve months of follow-up. In the last phase, the effect of Alerta Cannabis is evaluated. The primary outcomes are the lifetime prevalence of cannabis use and its use in the last 30 days and at 6 months. At 12 months of follow-up, the prevalence in the last 12 months will also be assessed. The secondary outcome is the intention to use cannabis.
CONCLUSIONS: The study tests the effect of the innovative program specifically aimed to reduce the use of cannabis in the adolescent population through eHealth in Spain. The findings aim to develop and implement evidence-based cannabis prevention interventions, which could support school prevention, for instance, the assistance of school nurses. If the program proves to be effective, it could be useful to prevent cannabis use on a national and international scale.
